Fleurieu dog and cat owners have just a few weeks left to renew registrations for their beloved pets.

Local councils have issued annual registration renewal notices via text, post or email for about 423,000 dogs and cats across the state.

Owners have until 31 August to complete the renewals in the state-wide register, Dogs and Cats Online, and pay any associated fees - or risk possible late fees.

More than a third of the dogs and cats registered in SA have already been renewed, according to the Dog and Cat Management Board, including a record of 100,000 within the first two weeks after renewals opened on 1 July.

In South Australia, all dogs and cats must be desexed, microchipped and registered.

Dog and Cat Management Board Chairman David Parkin says it is important that owners took the time to register their pets.

“It is encouraging that many owners have been so quick to renew registrations, but there are still plenty more to go,” Mr Parkin says.

“Annual renewals are a great time to check that your pet’s microchip details are updated with the correct contact details.

“For cats specifically, shelters have reported that 97 per cent of cats can’t be returned because owners have not registered a microchip in Dogs and Cats Online and kept information up to date.”

For assistance to register your dog or cat, contact your local council.
